This revised edition of Work and Services Contract Law (Werkvertragsrecht) is being published five years after the German Act to Secure Contractor Claims and Improve the Enforcement of Payment Claims (Forderungssicherungsgesetz) came into effect. Although the previous edition already took this amending law into consideration, the commentary has now been completely reworked with attention to decisions in case law and contributions to the literature that have taken place in the interim. Not only does the text offer a comprehensive analysis of relevant decisions by the German Supreme Court, but it also evaluates their implications for compelling problems that arise in legal practice. The book consistently inquires into the Supreme Court’s underlying dogmatic concepts and offers a range of alternative perspectives, while never forgetting the need for practical solutions relevant to actual practice. Some of the commentary is specifically directed to practitioners of construction law, meeting their particular needs by continuously interweaving the examination of the work and services contract law with consideration of construction tendering and contract regulations. In addition, the needs of practitioners are taken into account by providing separate appendices that deal with especially critical issues as they occur in practice, such as the impact of insolvency law on building contracts and construction law.
